Assyrian or Nestorian Church

The Assyrians are the remnants of the Nestorian Church that emerged
with the Christological controversies in the fifth century. The
Nestorians, who have a Syriac liturgy, stressed that Christ consisted of
two separate persons, one human and one divine, as opposed to having two
natures in one person. Their doctrine was condemned by the Council of
Ephesus in 431 A.D. Subsequently, those Nestorians who accepted this
doctrine formed an independent church, which has only a few thousand
members in Lebanon.
